BEYOND STATISM AND PERCEPTION OF THE COLD WAR, EXHIBITING THE LIVES AND MEMORIES OF PEOPLE

( Lee Sangrok ) 대한민국역사박물관 2021 Public History & Museum Vol.4 No.-

The History Gallery, the permanent exhibition at the National Museum of Korean Contemporary History, has been reorganized after consultation during the preparation process with a variety of experts in different fields. The direction of this reorganization is to introduce the lives of ordinary people in an easy manner to visitors, and distance itself from the state-centered understanding of modern and contemporary history. Exhibitions that show people, such as “Stories within History,” which is uniquely composed of eight themes, and “Oral History Collection,” which tells of contemporary memories of ordinary people at the time, are effectively realized. Despite new attempts and meaningful achievements in terms of exhibition technology, it is somewhat disappointing that the basic historical narrative of the History Gallery is similar to what can be found in middle and high school history textbooks and that too much information is listed. Nevertheless, the History Gallery will be remembered as a meaningful permanent exhibition in the National Museum of Korean Contemporary History, which aims for the democratization of memory.

Multi-attention-based soft partition network for vehicle re-identification

Lee Sangrok,Woo Taekang,이상헌 한국CDE학회 2023 Journal of computational design and engineering Vol.10 No.2

Vehicle re-identification helps in distinguishing between images of the same and other vehicles. It is a challenging process because of significant intra-instance differences between identical vehicles from different views and subtle inter-instance differences between similar vehicles. To solve this issue, researchers have extracted view-aware or part-specific features via spatial attention mechanisms, which usually result in noisy attention maps or otherwise require expensive additional annotation for metadata, such as key points, to improve the quality. Meanwhile, based on the researchers’ insights, various handcrafted multi-attention architectures for specific viewpoints or vehicle parts have been proposed. However, this approach does not guarantee that the number and nature of attention branches will be optimal for real-world re-identification tasks. To address these problems, we proposed a new vehicle re-identification network based on a multiple soft attention mechanism for capturing various discriminative regions from different viewpoints more efficiently. Furthermore, this model can significantly reduce the noise in spatial attention maps by devising a new method for creating an attention map for insignificant regions and then excluding it from generating the final result. We also combined a channel-wise attention mechanism with a spatial attention mechanism for the efficient selection of important semantic attributes for vehicle re-identification. Our experiments showed that our proposed model achieved a state-of-the-art performance among the attention-based methods without metadata and was comparable to the approaches using metadata for the VehicleID and VERI-Wild datasets.

탈식민 지식인의 구미歐美여행 경험과 자아 인식, 그리고 민족주체성의 재구축 : 1960~70년대 함석헌의 미국 ․ 유럽 여행기를 중심으로

Sangrok Lee 문화사학회 2011 역사와 문화 Vol.22 No.-

In 1960~70s, when Korean society was filled with longing for being modernized country, Ham Seok-heon was a rebel of the time, who criticized Western civilization view itself which distinguished ‘undeveloped’ from ‘developed’ by material civilization. Unlike other intellectuals who were overwhelmed by modern civilization, introducing the West as being universal or standard, following it, Ham Seok-heon, while traveling to the West, met the capitalist modern civilization the West built with a critical eye. He recognized a trip as an act of crossing differences between ‘You and I’ and ones between ‘These people and Those people’. It was an experience of looking for ‘I’ deeper by looking at ‘You’. He visited America and Europe with a critical attitude toward western material civilization, but after seeing it himself, he gave an ambivalent response. He felt and criticized avaricious capitalism through the trip and recognized that behind spotlessness of material civilization, there was violent relationship between the center and surroundings, in which the West left dirtiness of material civilization with so-called underdeveloped country of non-western areas. On the other hand, he envied America and Europe their comfortableness and richness, showing a desire to imitate and learn ‘steadiness’ under the spiritual base. Sometimes, he expressed such a desire in a vagarious way like imaging a glorious past of the Korean people, seeing the broad plain of America. This reflected the post-colonial period’s intellectuals‘ psychological complex. Every time he crossed borders, he criticized contradiction of civilization that humans themselves made a boundary of discrimination. While he intensely criticized nationalism, he wanted the Korea to be strong nation in religious and ethical aspects. He emphasized that the Korean people should be at the head of making new world history as a religious and ethical subject by throwing away western old civilization, not want to be a developed country by just accepting western civilization resulting in imperialism. It showed trauma and distinctive healing method of the Post-colonial period’s Korean intellectuals.

트위터 안의 정치 담론에 나타난 매개 유력자 분석

이상록(Sangrok Lee),이지연(Jiyeun Lee),성경(Cheng Qing) SBS 2012 미디어경제와 문화 Vol.10 No.4

정보통신기술(ICT) 발달로 소셜미디어(social media)의 영향력이 갈수록 커져 가고 있다. 본 연구는 2012년 4·11 총선 과정에서 논란이 됐던 민주통합당 김용민 국회의원 후보의 막말 논란과 북한 미사일 발사 위협, 투표라는 세 가지 주요 이슈를 중심으로 트위터 상에서 나타난 정치적 행위를 네트워크 구조상의 매개유력자에 초점을 맞춰 살펴봤다. 분석결과 유력자는 대부분 유명인이나 공인(公人)일 것이라는 생각과 달리 전체의 63%가 일반 개인(私人)인 것으로 나타나 뉴미디어 환경에서 일반인의 영향력이 커지고 있다는 것을 보여줬다. 또 매개유력자의 트윗 가운데 리트윗(RT)이 43%로 유력자가 리트윗(RT)으로 영향력을 발휘하는 것으로 나타났다. 매개유력자의 73%가 정부비판 성향으로 친정부 성향(23%)보다 3배 이상 많아 정부비판 성향의 트위터 매개유력자가 많다는 것을 실증적으로 입증했다. Due to the rapid development of the Internet and Information Communication Technology (ICT), the Social Network Service (SNS) gradually makes bigger and bigger influence. In this paper, we will describe how Twitter deliberate the political discourse in this whole new media circumstance, which as well focus on the mediating influential media structure. It presents recent matter of facts - rough words from Kim Youngmin- a candidate of United Democratic Party in the general election period of April 11th, 2012; the missile launching threat from North Korea and the referendum. The research shows that it tends to be the ordinary citizens which of 63% of the mediating influential people through these issue, not the famous or public ones as it"s supposed to be. Further more, 43% of the mediating influential people, who is found the specific 60 amount of Twitter, make their influence via Retweet (RT) access. And otherwise the 73% of the people tend to be anti government compared with 23% pro-government ones, which is more than 3 times.

원형편파 패치안테나에서 상부덮개의 다중 적층에 의한 효과 분석

이상록(Sangrok Lee) 대한전자공학회 2014 전자공학회논문지 Vol.51 No.3

본 논문에서는 원형편파 패치안테나에 상부덮개를 여러 층으로 적층함으로써 안테나 성능에 미치는 영향을 분석하였다. 지금까지 원형편파 패치안테나를 설계하기 위해서는 주로 단층의 상부덮개를 적용하거나, 여러 층으로 구성된 하나의 상부덮개를 적용하였고, 성능 분석시 안테나 축비를 거의 고려하지 않았다. 먼저, 상부덮개와 패치안테나 간의 공기층 높이에 의한 중심주파수의 변화를 분석하였다. 공기층 높이가 적을 때는 중심주파수가 낮은 쪽으로 천이하였고, 0.05λ0의 공기층 높이에서는 주파수 천이가 거의 없었다. 다음은 최적의 공기층 높이를 적용하여 상부덮개의 층수를 증가하면서 안테나 성능을 분석하였다. 상부덮개의 층수가 증가하면서 안테나 이득은 비례적으로 증가하지만, 안테나 축비는 점차적으로 악화되었다. 또한, 상부덮개의 유전체 두께가 증가할수록 안테나 이득은 증가하지만 안테나 축비는 급격히 악화되었다. 결과적으로 안테나 축비를 3dB 이내로 유지하면서 상부덮개의 층수를 확장하여 다양한 이득을 얻을 수 있는 안테나 설계가 가능함을 확인하였다. In this paper, we analyzed the effects by multi-stacking superstrates over the circular-polarized patch antenna. The previous works considered a single-layered superstrate or a superstrate with multiple layers, and did not almost consider the axial ratio at the performance analysis. First, the effect of center frequency shift is analyzed by the variation of air-gap height between patch antenna and superstrate. The center frequency is down-shifted at the smaller air-gap height and has almost the same frequency as patch antenna at the air-gap height of 0.05λ0 Second, the antenna performance is analyzed by multi-stacking superstrates with the air-gap height of 0.05λ0 As the number of multi-stacked superstrates increase, antenna gain has a linear increase and axial ratio is exponentially deteriorated. In addition, it has also been observed that the antenna performance has the same trend with the number of multi-stacked superstrates as the thickness of superstrate increases. Finally, we confirmed that it is possible to design the CP patch antenna with the scalable gain and less than 3dB axial ratio by stacking the superstrate.

1980년대 중후반 냉전 질서의 변화와 한국 자유민주주의의 행방3)

이상록 ( Lee Sangrok ) 강원대학교 통일강원연구원 2024 평화들 PEACES Vol.3 No.1

1980년대 한국의 자유민주주의는 보수주의 정치사상으로만 이해되었지만, 냉전 질서의 변화와 맞물려 자유민주주의는 다양한 스펙트럼을 드러내고 있었고 급진적인 사상과 접합되기도 했다. 이 논문은 냉전의 지각변동ㆍ해체와 남북관계의 변화가 요동치던 1980년대 중후반기 한국의 자유민주주의가 어떤 담론적 기능을 수행했는가 하는 문제를 분절되면서도 연관되어있는 세 가지 주체의 흐름으로 다루었다. 전두환ㆍ노태우 정권과 지배이데올로그들은 민주주의의 실질화에는 거의 관심을 두지 않은 반면, 급진적 저항운동의 공세에 맞서 자유민주주의를 체제방어의 수단으로 삼았다. 일부 지배이데올로그는 기존의 반공정책을 비판하면서 자유민주주의를 긍정적인 방향으로 정정하려는 시도를 하는 등 자본주의적 주체 만들기에 몰두하기도 했다. 김대중은 ‘비폭력 민주주의, 비용공 남북통일, 비반미 민족자주’를 내세울 만큼 자칭 ‘온건개혁주의자’였고, 기본적으로 시장경제를 옹호하는 자유주의자였다. 그는 분배정의 실현 등을 위해 경제민주화를 적극적으로 제기하였고, 냉전ㆍ분단이 유발하는 자유민주주의의 파행에 대해 비판적이었다는 점에서 대안적 자유민주주의자였다고 볼 수 있다. 민중민주주의를 주장했던 문익환은 1980년대 급진적 좌파운동의 흐름이 저항적 자유민주주의에 끼친 강력한 영향의 흔적을 보여준다. 그의 탈냉전적이고 탈식민주의적 태도는 시대의 고난을 받는 존재로서의 민중을 환기시키고 있으며, 동시에 민주주의의 문제가 한반도를 둘러싼 강대국들과의 불균등한 관계의 문제로부터 자유롭지 못함을 드러내고 있다. In the 1980s, Korea’s liberal democracy was understood only as a conservative political ideology, but in conjunction with changes in the Cold War order, liberal democracy revealed a diverse spectrum and was sometimes combined with radical ideas. This paper addresses the question of what discursive function South Korea’s liberal democracy performed in the mid-to-late 1980s, when the tectonic shift and dissolution of the Cold War and changes in inter-Korean relations were turbulent, through the flow of three separate but related subjects. While the Chun Doo-hwan and Roh Tae-woo regimes and ruling ideologues paid little attention to the substantiation of democracy, they used liberal democracy as a means of defending the system against the offensive of radical resistance movements. Some ruling ideologues focused on creating capitalist subjects by criticizing existing anti-communist policies and attempting to correct liberal democracy in a positive direction. Kim Dae-jung was a self-described ‘moderate reformist’ who advocated ‘non-violent democracy, unification of North and South Korea through non-communist relations, and non-anti-American national independence’, and was basically a liberal who advocated a market economy. He can be seen as an alternative liberal democrat in that he actively raised economic democratization to realize distributive justice and was critical of the breakdown of liberal democracy caused by the Cold War and division. Moon Ik-hwan, who argued for people’s democracy, shows traces of the strong influence that the radical leftist movement of the 1980s had on resistant liberal democracy. His post-Cold War and post-colonial attitude evokes the people as suffering beings of the times, and at the same time reveals that the problem of democracy is not free from the problem of uneven relations with the powerful countries surrounding the Korean Peninsula.

영화 <모비딕>에 나타난 기자의 사실적 재현과 저널리즘 영화 관습

이상록 ( Sangrok Lee ) 고려대학교 정보문화연구소(구 고려대학교 언론연구소) 2014 커뮤니케이션 科學 Vol.30 No.1

이 연구는 기자를 주인공으로 한 사실상 첫 한국 영화인 <모비딕>(2011)이 실제 기자의 모습이나 행동, 취재 관행 등을 얼마나 사실적으로 재현했는지 중점적으로 살펴봤다. 또 <모비딕>이 할리우드 저널리즘 영화에 나타나는 장르의 기존 관습을 얼마나 따르고 있는지, 저널리즘 영화에서 주요 소재로 등장하는 음모론이 <모비딕>에서는 어떻게 다뤄지고 있는지도 연구했다. 분석결과 <모비딕>은 기자의 외형적 모습이나 언어 사용 등은 상당히 사실적으로 재현했지만 취재 방식이나 취재원과의 관계 등 기자의 내부 세계 재현에는 실패했다. <모비딕>은 또 기자, 편집자, 취재원이라는 저널리즘 영화의 기존 관습을 대체로 충실하게 지키면서 음모론을 영화의 중심 소재로 쓰고 있는 것으로 나타났다. This study has investigated realistic reproduction of journalist in the first korean journalism movie < Moby Dick >, especially focusing on it's portrayals of the journalists' appearances, behaviors, their way of speaking and their in-depth routines when they gather facts or meet their news sources. This study also try to find whether < Moby Dick > follow traditional syntax of journalism movies in Hollywood as well as < Moby Dick > use 'conspiracy theory' as it's main subject. As a result of research, it was founded that < Moby Dick > succeeded in reproducing realistically journalists' appearances, behaviors and their way of speaking but it failed to portray journalists' 'inner world' such as in-depth routine or secrets ways related to their deep throat. This study also founded that < Moby Dick > followed faithfully the syntax of traditional journalism movies such as reporter, editor and story/source and also used conspiracy theory as a main subject in the movie as many other journalism movies usually do.
